Anyone who does swear that is not credible in my view
No-one swore that. The point is that for the accuser's version of events to be true a number of unlikely events have to have happened.
Deciding the facts is the jury’s job
Not entirely true. Under Australian law the court can legitimately look at whether a guilty verdict was open to the jury on the evidence presented. And, under UK law, the court can look at whether the judge should have directed the jury to acquit.
A pity the Prosecution didn’t have a more aggressive silk to rip into those witnesses and make them contradict themselves
They accepted the evidence of those witnesses because it was true. Pell did greet members of the congregation for 10-20 minutes at the door of the cathedral after services. It is the long-established practice of the church that the archbishop must always be accompanied whilst wearing his ceremonial vestments. It is the case that the sacristy is a hive of activity in the brief period when it is unlocked after a service. It is the case that it is unlikely that two robed choirboys would be able to leave the procession and re-enter the cathedral without being observed.
None of the witnesses could say for certain that these things were true on the date of the alleged offence. After all, it was a long time ago. They gave evidence that these things usually happened, not that they happened on the specific date of the offence. But if any one of these things happened that day the offence cannot have occurred.
It is also the case that the accuser's evidence at the trial was different from his evidence at the committal, where it became apparent that his original version of events was physically impossible.
those men, those survivors told the truth
Just to repeat, there was only one accuser in this case. The other person he named as being abused died of an accidental heroin overdose. Before his death he specifically denied that he had been abused.
It may be that Pell is guilty but, having read both the judgement of the Victoria Supreme Court and this judgement, my view is that he should never have been convicted.
